Each node creates it´s own unique safety net, based on it´s consumption from other nodes that are connected to the network.

The idea is that consumption outside the network disconnects people from the network

This old video shows how I think:

I´m developing a simplified system as a proof of concept

for the duration it takes to receive that amount in dividends. Whenever a node consumes from nodes outside the network, they get disconnected until they´ve missed out on dividends equal to the amount they consumed for. Consuming outside the network disconnects nodes from basic income. it also disconnects them from taxing, which in turn disconnects them from costumers who want to consume from nodes within the network. In other words, if I consume for $1000 USD from someone outside the network, I´ll be disconnected for the next $1000 in basic income that people receive, and I´ll be disconnected from paying tax too, so corporations or producers loose consumers.

The incentive layer is one alternative, laws being the other, and completely voluntary based being the third. I think #DApps with all three options should be available in the "bitNation" #DApp-store.
